dbus-crossroads is a library that helps you implement interfaces on object paths, i e "server side" method handler code.

To get started, you can jump into the commented examples, one for sync one for async (dbus-tokio), and one slightly more advanced, or familiarize yourself using the API reference.

It supersedes the dbus::tree module. Design decisions (compared to dbus::tree):

• First class support for both sync and async methods
• Detect method arguments automatically through generics
• ...but less generics in structs you use, which means less cluttered API
• The tree/crossroads instance is Send (but not Sync).
• You can now modify the instance from within a method handler
• It is objects (paths) that can contain custom data, and they can contain different data for different objects
• Interface descriptions are kept in a registry, which means less reference counting
